Propagation of the Gaussian Beam in Bessel Optical Lattices
The numerical analysis of the dynamics of a Gaussian beam in Bessel lattices which are induced by transvering the focusing photorefractive nonlinearity crystal is presented. The propagation properties of the Gaussian beam can be different with and without the lattices. In the absence of the lattice, the beam will present linear diffraction and nonlinear focusing in a homogeneous medium. The beam can overcome these effects in a homogeneous medium after transfering in a crystal with lattices. With different initial input conditions in the case of lattices, the input beam can overcome these effects and form a ring-shaped soliton or a circle-shaped soliton.
